And is there someone which had tried to rollback with HiSuite ? I hesitate. On my side, hisuite propose me to rollback to b386, which may be OK, but I don't want to take risks...I need to be sure it will work

Do you already have a solution? I've a rollback package for C432B560 on my Home-PC, downloaded from a spanish forum.. The ones from OP Post didn't work for me. If you want to I can upload it anywhere.

Back from C900 to C150. How?

Hello,
I try to upgrade from c150b123 to c150b160 but obviously I failed. I flash C150, so I dont know where was the problem...
I read that is void my warranty. Is that a true?
What can I do to resolve this problem?
Sorry for my English!

I think you can use Huawei RollBack package using 3 buttons method and then flash c150b160 using the same method.
The rollback package and firmware image can be found on huawei site. Use google.

There is just Asia version of Rollback. I need to flash that?

As far as i know the region of the rollback package doesn't matter. I'm on c432 and used this
http://download-c1.huawei.com/download/downloadCenter?downloadId=93800&siteCode=pl
Be careful with the firmware image to be the right one (c150)

Thanks for helping! I didn't mention that I have L31 version. Or I can flash that for L21?

No, don't flash l21. The model matters. Download from huawei website rollback pckage for l31. The model does matter.
Forgot to ask you. You're on stock recovery ?

Yes, everything is stock. And b160 is Marshmallow, not Nougat.
b12x has many bugs and I just want to fix them , because my carrier didn't release update from september...

Oh yes sorry my bad. Then you don't need the rollback package. In this case the best option is to use firmware finder to update a full ota via system update.

I use firmware finder and got this problem although I check hundred times to use correct upgrade zip. I am scared to repeat update procedure because I don't want to brick my phone... :/
I guess I will have to take a risk.

You have to get the full ota update (with mf and pv in update name).

Better let someone else handle the updating, seeing as you're don't like reading too much.

Dude use Firmware Finder app and dns/vpn method
to try to force the upgrade ( try to use B361 FULL OTA-MF PV first ).
If all will take right direction, then use same method to update to
B502 (dual sim) or B503 (single sim) FULL OTA-MF version.
See the attachtments and good luck.

Dear,
huawei never planned to forward oreo official upgrade to p9 lite ( 2016 aka venus model ) users,
so do not waste your time looking for this, it simply doesn't exists...
B502 ( dual sim ) / B503 ( single sim ) are latest Nougat firmware.
Cheers

Firmware Finder is down bro, definitively. You can try to upgrade using dload method. Download Service ROM for dual SIM
and flash it, instructions can be found in ReleaseDoc folder. This process will erase all your data (and lock the bootloader again) !
I hope you have Dual SIM variant. If not, let me know.

Okay sounds cool I'll rebrand the question remained is what brand has the latest update?(Please provide a link to .zip update) and the last question is,if I rebrand before I install oreo what exactly happens I turn on my phone and it has a frimware from Africa but its brand is now China!Will that be able to turn on?Or I should use TWRP to install Chinese firmware from SD card.

Since I'm an android developer I need to have multiple os if possible.Has anyone tried this Or any better one?Can I use it in this case?

I have the firmware finder it found no FULL OTA from marshmelo the first full ota is for nougat.
http://update.hicloud.com:8180/TDS/...2227/f2/full/hw/eu/update_data_full_hw_eu.zip
The links from hicloud says that the files have been deleted.
I don't have a reliable internet connection I rather download zip files then update because I don't want in the middle of the operation things go wrong that's why I didn't try HiSuite.Any live link would be appreciated.
I found NXT-L29BC185B200 live link right now.It's android 6.0.1 I'll go for it tnx.

I download B200 tried to install via dload failed said (incompatiblity with current version ) tried with twrp failed.And I wiped my OS and tried again and failed.And lost my OS.Sort of now it shows me android logo instead of huawie logo and it's stuck on the initial setup of nougat.
https://forum.xda-developers.com/mate-8/general/guide-how-to-downgrade-mate-8-emui-5-to-t3515202
I found this and it says the nougat version must be b500 but mine was b560 and tried to install the rollback and it failed again.I don't know what to do?I need my phone.
Couldn't find any download link of b500 did you do that on your b500 or b560?
If b500 please give me a link of NXT-L29C185B500

Tried again and it didn't give me error this time the point is that it doesn't run on B500 it makes your device B500!

After installing marshmellow the bootloader is locked again!

Hello,
this happened because you
choose that firmware...
you are very lucky you didn't bricked your device.
You could try to use Firmware Finder again
to revert back to your previous version,
but as i told, you could brick it,
that's your choice.
Another way is unlock the bootloader,
install a custom recovery (TWRP),
flash an OEMinfo file and your correct firmware.
It depends on the android version,
on the region (CUST) in which you live
or for which the firmware has been released
and if the device is single or dual sim.
Good luck dude !
P.S.: took a look and it seems
the link for Hassan's twrp download
is no longer available...
Maybe other twrps are still available,
but i'm pretty sure someone could
repost it for you...

You can try flash it with Service ROM Download . Type VNS-L31, or VNS- .
Download correct firmware - EMUI version, Cxxx (the bracketed (Cxxx) is your device’s regional variant.
This number is very important in determining the correct firmware to download. Select your previous Cxxx, not current C00 ) and single/dual SIM (all firmwares that end with even numbers are for dual SIM, odd numbers are for single SIM).
Instructions can be found in 'ReleaseDoc' folder.
If you cannot unpack downloaded zip archive on PC, unpack it in the internal memory using this RAR apk.
Extracted 'dload' folder copy/transfer to the SD card. Good luck.
